File Insight problem

I have had to reinstall windows 10 due to an update that messed the system up. Since refreshing, my PC has been doing some strange things, one of which is playing games with file insight. When installing software such as iTunes, file insight keeps popping up with a "needs attention" message and says that the iTunes.exe is a rare file. However, when the program is installed, the message turns green. I have never noticed this before and am convinced that it's due to some sort of software conflict somewhere. Please could someone help with this issue.
